Message	All of the ECU's supported by NIStune are limited by the 16x16 resolution. It's a hardware bound limitation as the ECU use a 27C256 EPROM which can only address 128 addresses for each of the 256 pages of raw data. Hence, 16x16=128 addresses. Basically ConVerTT was simply referring to changing the default or preprogrammed values contained within the 16x16 map range on the x and y axis. 364 RWHP & 480 RWTQ VG30ET Member "Ahh, to have the pos 323 appreciated by a 30k evo owner." -SactoTodd
